Abstract
Description
Die Erfindung betrifft ein Mammographiegerät, insbesondere die Ausgestaltung einer Röntgeneinheit bei einem Mammographiegerät, bei dem der Patient brustseitig auf einer Liegefläche einer Liegeeinheit während der Röntgenaufnahmen positioniert ist.The invention relates to a mammography device, in particular the embodiment of an X-ray unit in a mammography device, in which the patient is positioned on the breast side on a lying surface of a lying unit during the X-ray recordings.
Um in der liegenden Position von der Brust des Patienten eine Röntgenaufnahme zu erstellen, weist die Liegeeinheit in Höhe der Brust eine Öffnung auf. Die Brust wird zu einer Röntgenaufnahme zwischen der Röntgeneinheit und einem Detektor der Röntgeneinheit positioniert. Um von der Brust der Patientin eine Vielzahl von Röntgenaufnahmen aus unterschiedlichen Winkelpositionen zu erstellen, wird ein Röntgenkopf auf einer Kreisbahn um die zu untersuchende Brust geführt. Zur Positionierung des Röntgenkopfes und des Detektors ist eine Mechanik nötig die unterhalb des Behandlungstisches angeordnet ist. Die Mechanik bringt jedoch den Nachteil mit sich, das aufgrund von Bewegungsartefakten die Qualität der Röntgenbilder reduziert wird. Neben der aufwendigen Mechanik muss der Röntgenkopf und ein mitgeführter Hochspannungsgenerator mit elektrischer Energie und einem Kühlmedium versorgt werden. Dies bringt den Nachteil mit sich, dass die Bewegungsfreiheit um die Behandlungseinrichtung für Arzt und Behandlungspersonal eingeschränkt ist.To make an X-ray in the lying position of the patient's chest, the lying unit has an opening at the level of the chest. The breast is positioned to an X-ray photograph between the X-ray unit and a detector of the X-ray unit. To create a variety of X-ray images from different angular positions of the patient's chest, an X-ray head is guided on a circular path around the breast to be examined. To position the X-ray head and the detector, a mechanism is necessary which is arranged below the treatment table. However, the mechanics have the disadvantage that the quality of the X-ray images is reduced due to motion artifacts. In addition to the elaborate mechanics, the x-ray head and a high-voltage generator carried along must be supplied with electrical energy and a cooling medium. This has the disadvantage that the freedom of movement around the treatment facility for the doctor and treatment staff is limited.
Der Erfindung liegt die Aufgabe zugrunde, ein Mammographiegerät unter Vermeidung der oben aufgeführten Nachteile anzugeben.The invention has for its object to provide a mammography device while avoiding the disadvantages listed above.
Die Aufgabe wird durch die im Patentanspruch 1 angegebenen Merkmale gelöst.The object is solved by the features specified in claim 1.
Die Erfindung bringt den Vorteil mit sich, dass die Röntgeneinheit stationär angeordnet werden kann und dadurch die Qualität des Röntgenbildes durch Bewegungsartfakte nicht vermindert wird.The invention has the advantage that the X-ray unit can be arranged stationary and thereby the quality of the X-ray image is not reduced by Bewegungsartfakte.
Die Erfindung bringt den Vorteil mit sich, dass durch den Wegfall der mechanischen Komponenten zur Bewegung der Röntgenröhre ein erheblicher Platz für System- oder Behandlungskomponenten bereitgestellt werden kann.The invention has the advantage that a significant space for system or treatment components can be provided by the elimination of the mechanical components for moving the X-ray tube.
Die Erfindung bringt den Vorteil mit sich, dass sowohl eine Tomosynthese wie auch eine Dual Energy Bildakquisition auch ohne bewegte Teile durchführbar ist.The invention has the advantage that both a tomosynthesis as well as a dual energy image acquisition is feasible without moving parts.
Die Erfindung wird im Folgenden mittels der in den Zeichnungen dargestellten Ausführungsbeispiele näher erläutert.The invention will be explained in more detail below by means of the embodiments illustrated in the drawings.

Die Multifokusröhre ST, ST1, ST2, STKS, STK kann auch in der Art ausgestaltet sein, dass diese jeweils ein Feld von Röntgenröhren aufweist. Mit dieser Ausgestaltung können dann auch Dual Energie Röntgenbildsequenzen aufgenommen und/oder Volumenbilder erstellt werden.The multi-focus tube ST, ST1, ST2, STKS, STK can also be designed in such a way that each has a field of x-ray tubes. With this embodiment, then also dual energy X-ray image sequences can be recorded and / or volume images are created.
